A research scientist wants to know how many times per hour a certain strand of bacteria reproduces. He wants to construct the 98% confidence interval with a maximum error of 0.15 reproductions per hour. Assuming that the mean is 10.8 reproductions and the standard deviation is known to be 1.8, what is the minimum sample size required for the estimate? Round your answer up to the next integer.

Pschological tests are often used to determine the hostility levels in people. High scores on the HLT pschological test corresponds to high hostility levels. Suppose that 26 college students, all with equally high HLT test scores, were separated into two groups randomly. Group 1 (10 students) was treated for high hostility levels by using Method A; whereas Group 2 (16 students) was treated for high hostility levels by using Method B. Both groups were treated for a period of 5 months, at which time all 26 students were again given the HLT test. Below is the summary data on the HLT test for the two groups.Group 1: sample mean is 79 and sample standard deviation is 7Group 2: sample mean is 84 and sample standard deviation is 8Compute a 95% confidence level for the difference in the means of the two treatment methods and select the best answer below. Assume that the independent random samples were taken from normal distributions and that the two population variances are equal.

At 12:00 in the afternoon Paul stopped at the gas station and filled his car 50-liter tank to capacity. After Paul drove 75 miles away from the station, the tank developed a leak and the car started to lose 15 liters of fuel per minute. If Paul is traveling at a constant speed of 50 miles per hour and his car consumes 10 liters per every 100 miles, at what time of the day will Paul run out of gas?
